The document discusses network architecture components, traditional network design, and building block network design. It asks to pick two network simulation tools from the list provided and discuss and present them in class. The list includes WANsim, OPNET Modeler, NS2, NS3, OMNeT++, REAL 5.0 simulator, SSFNet, J-Sim, QualNet, YANS, and GTNetS.

1. Explain and provide example when it is possible that will cover
chapter 6 subjects:
•Network architecture components
•Traditional network design
•Building-block network design
–Needs analysis
